Thanks for that - I've achieved linker happiness.
FYI, I notice that the GCTest stub file has a do..while(0), which I suppose
should be optimised away by GCC, but still makes the code less
palatable:
--------------------------------------------------------
/* Auto generated GreenCard 2 code for FFI */
double prim_my_sin(double arg1)
{ double res1;
do { res1=sin(arg1);
return((double)(res1));} while(0);
}
--------------------------------------------------------
